CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 246,565, dated August30, 1881.

Application filed July 15, 1831. (No model.)

To all whom it may concern:

Be it known that I, HARVEY SMITH, a citizen of the United States,residing at Oott'eyville, in the county of Montgomery and State ofKansas, have invented certain new and useful Improvements inGar-Couplers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters orfigures of reference marked thereon, which form a part of thisspecification, and in Which- Figure 1 is a side elevation, and Fig. 2 isa horizontal longitudinal section, ofmy improved car-coupling, and Fig.3 is a detailed perspective view of the same.

This invention relates to improvements in car-couplings, its objectbeing to insure the falling of the pin and the coupling of the ears, andit consists of a tubular right-angled arm, having a shaft passing downinto the drawhead, and provided with a cam or projection adapted tostand in the way of the incoming link, and when struck by the link to socontrol the movement of the arm which carries the pin as to bring thearm with the pin in the line with and permit the falling of the pinthrough the aperture in the draw-head, and to secure the link,substantially as hereinafter more fully set forth and claimed.

Referring to the accompanying drawings, A is the draw-head, of the usualconstruction. B is a right-angled arm or holder for the pin,with itsvertical portion provided with an aperture, 1), extending through it toreceive the pin (J. The pin 0 is constructed of round or flat metal,with an offset or shoulder at a sut'ficient distance from the lower endto rest upon and support the link in a position to enter the drawhead Aas the cars come together. The rear turns in the draw-head A. This shafthas awing or cam, c, affixed to the same at such an angle as that whenthe tubular part of the holder B, with its pin, is swung out of line orto the side of the pin-hole in the draw-head, supporting the pin in anelevated position upon the latter, it will stand in the way of theincoming link, and when struck by the link will swing the tubular partof the arm or holder, with the pin, around in line with the pin-hole inthe draw-head. When the pin reaches this point it will fall into theoblong opening of the link,and thus securely couple the cars. A recessis provided in the draw-head to permit the wing or cam to swing in as itis struck by and to allow the link to pass it. A chain, (1, connects thepin to the arm, and to this chain is suspended a small pin, 6, which isinserted into an aperture, e, in the coupling-pin when it is required tosupport the latter, which becomes necessary to keep the cars uncoupledwhen in close proximity.

Having thus fully described my invention,I claim and desire to secure byLetters Patent In a car-coupling, the draw-head A, provided with the pin0, the right-angled tubular pinholder or arm B, having the shal't B,provided with the wing or cam c,adapted,when the arm with thecoupling-pin is out of line with the pin-hole in the draw-head,to standin the way of the incoming coupling-link, and when struck bythe link toswing the arm and thepin around and allow the pin to drop into thepin-hole in the draw-head, substantially as and for the purposedescribed.

In testimony whereofI affix my signature in presence of two witnesses.
